Yes, zero-entry pools are also referred to as beach-entry pools because the gentle slope leading to the water mimics the natural slope of a sandy shore leading to a lake or ocean. You can bring in sand or pebbles to truly capture the beach-like feel of a zero-entry pool.

It depends. Your pool might need chlorine every day if the water is exposed to direct sunlight and you use your pool frequently. UV light and constant use will deplete chlorine levels more rapidly. Test your water regularly to see where your levels sit and adjust accordingly. Generally speaking, most homeowners need to add chlorine following a water chemical test about one to three times per week.

An easy way to know whether your sand filter has enough sand is to check how full the filter is and what the sand looks and feels like. The filter container should be two-thirds to three-quarters full of sand. Look for interior marks indicating the ideal sand level. If you put your hand into the sand, it should flow through your fingers without clumping. The filter pressure gauge is also an easy indicator—the right amount of sand leads to normal pressure, while too much or too little sand can cause high or low pressure.

There are some disadvantages to a salt water pool. Besides costing slightly more than chlorine pools, salt water pools require a lot of salt. It's also harder to find a professional with salt water pool experience to do minor maintenance and repairs. Salt water can also damage some materials, so you’ll need to use specific heating, fixtures, lighting, liners, and masonry when building a salt water pool.
